Patio Cover Design Questions

I realize there are a number of Pergola posts; however, I couldnt find the info I needed. Hope another one if ok?

I plan to build a 16 x 16 ft. Pergola over a paver patio 18 x 18 feet. I would appreciate any comments on the design and materials. I have not decided between Cedar and PT. My preference is Cedar; however, the available dimensions and cost make it a challenge.
